Introduction

Task:

– Design and realize an extension to the Smart Kiosk project which will detect presence of a person. – Utilize the OPENCV library and a camera. – Part of the design will be a scenario taking advantage of this information.

Implementation

Used technologies:

– C++ (no virtual machine code bloat and required by OpenCV anyways...) – OpenCV (face detection, recognition and other image processing) – Nokia Qt (GUI) – Windows Sockets (client/server communication) – DirectShow (video overlay drawing)

Task distribution

Server:

– Receives image data from clients – Performs face detection and recognition – Holds user registration data – Sends recognition results to clients

Client:

– Displays the results – Shows forms for login, registration, etc.

Used face recognition in detail

Face detection: Viola and Jones (based on Haar

wavelets)

Face recognition:

– Eigenfaces – Principal Component Analysis (PCA)

Does it work?

It works quite well :) (for a one semester

long assignment, that is)

– Reasonably stable lighting conditions are required – At least two people (I mean their face images) are required to create working face recognition data
